This invention relates to automatic mechanism for producing runninglengths of decorative material. Such material, in one form thereof,comprises lead or tin foil out in such manner asto provide a fringependant from a marginal portion thereof, said marginal portion beingprovided with a reenforcing binding which, in most cases, includes aflexible cord or strand extending through the bight thereof. The machineis also operative to produce a crinkling or crimping of the individualfringe forming appendages or elements, whereby. in the finishedmaterial, the fringe is furnished with a multiplicity of lightreflecting facets so that a brilliant scintillating effect is attainedby the reflection of light therefrom when the material is employed inuse as an ornamental trimming or for other decorative purposes. 7

The invention has for its general object to provide a simple, cfficientand compact machine adapted to automatically and rapidly fabricate theelements making up decorative material of the type above referred to,and to produce the crinkled or crimped fringe structure of saidmaterial.

The invention has for an object to provide, in a machine of the kindabove referred to, means for automatically and continuously withdrawingfrom a source of supply the various elements entering into theconstruction of said decorative material and thereupon bringing saidelementstogether in proper assembled relation, and then advancing theassembled structure to and through a novel cutting or shearing mechanismadapted to produce in the lead or tin foil element a pendant fringestructure.

The invention has for a further object to provide, in such machine,means to crimp the fringe forming members whereby the fringe iscorrugately crinkled to provide the same with angular light reflectingfacets to thus render the fringe of sparkling effect in use.

Other objects of this invention not at this time more particularlyenumerated will be understood from the following detailed description ofthe same.

An illustrative embodiment of the invention is shown in the accompanyingdrawings, in which:

Fig. 9 is a fragmentary sectional view of a modified form of foil guiderod means.

Similar characters of reference are employed in the above describedviews, to indicate corresponding parts.

Referring to the drawings, the reference character l0 indicates a bottomframe plate and II a top frame plate, said plates being secured togetherin vertically spaced relation by intermediate vertical frame bars l2extending between the respective corner portions thereof.

At its left hand end portion, as viewed in the 20 drawings, the topframe plate H is cut away to provide an opening l3 therethrough. This.opening I3 is bridged over by a bridge plate M which is suitably securedto said top frame plate II by bolts and nuts 15. At its inner lateralmarginal portion said bridge plate I4 is cut away to provide a hatchwayor passage 16 leading to the space beneath said top frame plate I l.

Afiixed to said bridge plate It is a bearing housing IT in which ismounted a suitable anti-fric- 0 tion bearing l8. Journaled in saidbearing I8 is a rotatable upper spindle [9, which is retained inoperative relation to the bearing I8 and its housing H by a keepercollar 26 suitably secured to its exteriorly and upwardly projectingfree end portion. Threaded to and extending axially through. saidspindle I9 is an adjusting member 2!, to the lower end of which isattached a conical hub member 22. Said hub member 22 is disposed beneaththe top frame plate ll. Connected with the bottom frame plate In is abearing housing and bearing 23 similar in kind to the housing I1 and itsantifriction bearing I8, and journaled therein is an upstandingrotatable lower spindle 24 which is disposed in vertical or axialalignment with the upper spindle I9. Engaged on and carried by saidlower spindle 24, so as to be vertically adjustable thereon, is a foilroll supporting sleeve 25 having at its upper end a conical hub member26. A supply of lead or tin foil F, in the form of a roll 21 thereofwound upon a hub sleeve 28, is provided to supply this material subjectto the operation of the machine. This roll is mounted over the lowerporting sleeve 25 engages wedgingly in the lower end of its hub sleeve28, while the hub member 22 of the upper spindle i9 engages wedgingly inthe upper end of said hub sleeve 28, thus rotatably mounting the foilsupply roll so that the foil may be drawn from the same. Said supportingsleeve 25 is provided with a manipulatable-thumb-screw 2% whereby thesleeve may be aflixed to the lower spindle 24 in desired adjustedposition according to the height of the particular foil supply roll tobe used. The hub member 22 of the upper spindle I9 is verticallyadjustable so as to dispose the upper marginal portion of the foilmaterial in proper alignment and registry with the operative mechanismsof the machine through which the foil material is to be passed.

Secured to and extending between the bottom and top frame plates H3 andH are one or more foil guide rods 36, at least one of which is disposedto direct the leading end of the foil into the proper path of movementto be traversed by the same when subjected to the action of theoperative mechanisms of the machine.

Fixed upon the bridge plate I4 is an upstanding bracket 3! whichsupports a transversely disposed spindle 32. A supply of binder tape T,in the form of a roll 33 thereof, is rotatably mounted upon said spindle32, so that said binder tape may be drawn from said roll and suppliedsubject to the operation of the machine.

Suitably affixed to the top frame plate H, in upstanding relationthereto, is a post 3 having affixed thereto a supporting flange 35 abovewhich projects a vertical spindle 35. A supply of flexible cord or likematerial C, wound e. g. upon a spool 31, is provided to supply thismaterial subject to the operation of the machine. The spool 3! isrotatably supported by the flange 35 and spindle 3% so that the cord Cmay be drawn from the spool and fed with the foil F and binder tape Tinto the machine.

The binder tape T extends from the roll 33 thereof downwardly throughthe hatchway or passage 5 provided in the bridge plate it, while at thesame time cord C extends from spool 3 3' to pass through a guide opening38 provided in the bridge plate M behind the hatchway or passage !6, sothat the cord is fed with and beneath the binder tape T.

Mounted on the underside of the top frame plate H beyond the hatchway orpassage IE is a tape folding and applying means adapted to fold the tapealong its longitudinal axis so as to both envelop the cord C in thebight of such fold and embrace within the fold of the tape the upperlongitudinal marginal portion of the foil, thus assembling thesematerials together in the desired manner subject to progressive movementthrough the machine for subsequent fringing and crimping operations.

The tape folding and creasing means comprises a pair of rotatablepressure rolls including a stationary roll 39 and an opposed adjustableroll 46. These rolls rotate about vertical axes adjacent to theunderside of said top frame plate I l. The shaft ll of the stationaryroll (-29 is journaled in a bearing sleeve 4! fixed in said top frameplate I I, and said shaft 4! is provided at its upper end with a drivingsprocket 42. The shaft 43 of the adjustable roll it is journaled in abearing sleeve 44 fixed in a transversely disposed bearing carrier 45,the latter being slidably disposed between guide pieces d6 upon theupper surface of said top frame plate ll. Said top frame plate H isprovided with an opening 5'! to provide adjusting clearance for saidbearing sleeve 44 which extends therethrough. The means for adjustingsaid bearing carrier 55 comprises a stationary bracket 48 which issecured to the top frame plate H. Threaded through the upstanding lug 49of said bracket 48 is an adjusting screw 50, the shank 5| of which has aswivel connection with the upstanding lug 52 of said bearing carrier 45.Said shaft 43 of the adjustable roll if! is provided at its upper endwith a driving sprocket 53. By adjustably moving the bearing carrier 45,the roll 40 may be moved toward or from the stationary roll 39 so as toadjust the nip of the rolls for the proper reception, passage andtreatment of the materials passed to and between said rolls. Afiixed tothe underside of said top frame plate H, in advance of said pressurerolls 39-9, is a folder member 54, the converging sides of which extendtoward and adjacent to the nip of the pressure rolls 39i0, so that asthe horizontally entering tape T passes into and through said foldermember, accompanied by the underlying cord C and the upper marginalportion of the foil F, the side marginal portions of the tape,oppositely extending from its longitudinal medial line, will begradually downturned and folded respectively over opposite faces of theupper marginal portion of the foil F, thus forming the tape into abinding which embraces the foil material, while at the same timeenclosing the cord C in longitudinal extension through the bight or foldof the binding thus formed. The under surface of the tape is providedwith a suitable adhesive which will adhere the fold thereof to thesurfaces of the foil F under the pressure applied to the folds by theaction of the pressure rolls 39- 40. The pressure rolls 39-40 not onlyaid in drawing the materials from the respective supplies thereof, butalso, while creasing and ironing down the folds of the binder tape intosmooth adhering relation to the foil F, also assist in advancing thethus assembled materials onwardly through the machine subject tosubsequent operations.

Beyond said pressure rolls 39- l0 is arranged a pair of rotatable feedrolls which extend vertically between the bottom and top feed platesl0l|. Said feed rolls comprise a stationary feed roll 55 and an opposedadjustable feed roll 56. provided with a journal 57 extending upwardlythrough a bearing sleeve 58 which is fixed in said top frame plate ll.Affixed to the upper free end of said journal 5'? is a driving sprocket59. Mounted in connection with the bottom frame plate i6 is a journalstud 60 to rotatably support the lower end of said stationary feed roll55 in connection with a suitable anti-friction bearing M with which saidlower end portion of the latter is provided. At its upper end, saidadjustable feed roll 56 is provided with a journal 62 extending upwardlythrough a bearing supported by an adjustable bearing carrier 63, and atits lower end, said adjustable feed roll 56 is rotatably supported by ajournal stud and anti-friction bearing, similar to those serving thestationary feed roll 55, and carried by a corresponding adjustablebearing carrier 63. Said bearing carriers 63 are similar in constructionto that abovedescribed as supporting the adjustable creasing roll til,being slidable between guide-pieces 64, and being subject to adjustingmovement by means of adjusting screws 65 which are threaded throughbracket pieces 66 affixed to the frame plates. By adjustably moving thebearing car- At its upper end, the stationary feed roll is I riers 63,the feed roll 56 may be moved toward or from the stationary feed roll 55so as to adjust the nip of these rolls properly to the assembledmaterials passing therebetween. A drive sprocket 61 is afiixed to theupper journal 62 of the adjustable feed roll 56. To efiect a positivegrip and feed of the materials through and by said feed rolls 5556, theadjustable feed roll 56 provided, adjacent toits upper end, witha plurality of circumferentially spaced radially pro-- jecting drive pins 68,and the stationary feed roll 55 is provided with a cooperating annularclearance groove or channel 69 toreceive and pass said pins. Said drivepins 68 are sharply pointed, and,

r consequently, as the tape bound margin of the foil F passes betweenthe feed rolls 55-56, said pins will laterally pierce the same, thuspositively engaging and propelling forward the material, since thesepins enter the material as it approaches the nip of said feed rolls andwithdraw therefrom as the material leaves the nip of and rolls.

Beyond said feed rolls 5556 is arranged foil slitting or shearing meanswhereby the body of the foil material extending below the tape boundmarginal portion thereof may be cut to provide a dependant fringe. Thisslitting or shearing means comprises a rotatable vertically disposedcutter roll 10 having at its upper end a journal H which extendsupwardly through a bearing sleeve 12 mounted in the top frame plate ll.Aflixed to the upper free end of said journal TI is a driving sprocketl3. Mounted in connection with the bottom frame plate 10 is a journalstud 14 to rotatably support the lower end of "said cutter roll 10 inconnection with a suitable antifriction bearing 15 with which said lowerend portion of the cutter roll is provided. At its upper end portion thecutter roll 10 is provided with a plurality of circumferentially spacedradially projecting drive pins 16 to engage and propel the tape boundmarginal portion of the foil through the slitting or shearing means ofwhich the cutter roll is a part. The cutter roll is provided,

around its cylindrical surface, with a plurality of radial cuttingelements 11, which extend longitudinally of the roll. These cuttingelements are somewhat obliquely inclined to the axis of the roll, forpurposes presently to be explained. Cooperative with said cutter roll isa rotatable vertically disposed backing roll 18 against the cylindricalsurface of which the sharp knife-like edges of the cutting elementsimpinge, so as to shear through the foil material as the latter isbacked or supported by the backing roll when passing between the sameand said cutter roll. At its upper end, said backing roll 18 is providedwith a journal H! which extends upwardly through a bearing sleevesupported by an adjustable bearing carrier 8|, and, at its lower end,said backing roll is provided with an anti-friction bearing 82 inconnection with which it is rotat ably supported by a journal stud 83carried by a corresponding adjustable bearing carrier 84. The bearingcarriers 8| and 84 are respectively slidably mounted upon the top andbottom frame plates for movement between guide-pieces 64, and theadjusting movements of said carriers are controlled by adjusting screws85 which are threaded through stationary brackets 86 respectivelyaffixed to said top and bottom frame plates. By adjustably moving thebearing carriers 8l-B4, said backing roll 18 may be positioned relativeto the cutter roll H1 in such manner as to assure .a proper impingementthereupon of the cutting elements 11. A drive sprocket 81 is affixed tothe upper journal 19 of said backing roll. At its upper end portion,thebacking roll 18 is provided with an annular clearance groove orchannel 88 to receive and pass the drive pins with which said cutterroll is provided. l

In the operation of the machine, as the foil F is advanced to and passesbetween said cutter roll 10 and backing roll 18, that portion of thefoil body dependant from. its tape bound upper marginal portion isengaged between the knifelike edges of the cutting elements 11 and thesurface of the backing roll 18. Owing to the oblique disposition orinclination of the cutting elements 1'! relative to the vertical axis ofthe backing roll 18, the point of impingement of each cutting elementedge shifts longitudinally along the backing roll surface as the rollsrotate. The result of this mode of operation is to cause the cuttingelements to progressively cut through the foil material with .a shearingaction as distinguished from a chopping cut involving the simultaneousaction of the entire length of a cutting edge at the instant ofimpingement upon the backing roll as would be the case if the cuttingelements Tl were arrangedparallel to the axis of the backing roll.Preferably the inclination of the cutting elements 71 is from left toright leading from the upper end of the cutter roll 10,

which, as shown, rotates in a clockwise direction, 3

since by such disposition the cutting elements are caused to sheardownwardly through the foil body from. a selected point adjacent to itsupper bound marginal portion. The described arrangement of the foilslitting or shearing means assures a clean cut with minimum risk oftearing or undesirably mutilating the foil, and consequently a clean cutfringing of the foil body to a desired depth or extent is easilyattained without risk of the fringe elements failing to be released frombetween the cutting elements or teeth; the width of the fringe elementsbeing determined by the spacing of the cutting elements Tl around thecutter roll circumference.

Beyond the foil slitting or shearing means, the machine is provided withmeans for crimping the cut fringe, to thereby corrugately crinkle thefringeelements transversely, whereby light reflection from the fringeproduces a sparkling or scintillating effect. This crimping meanscomprises a pair of rotatable vertically disposed crimping rolls. Thesecrimping rolls comprise a stationary female crimping roll 89 and anopposed adjustable male crimping roll 90. The surfaces of said rolls areprovided with annular corrugations; those of the male crimping roll 90mating or dove-tailing with those of the female crimping roll 89. One ofthe rolls, as e. g. the female crimping roll 89, is provided at itsupper end with a journal 9i which extends upwardly through a bearingsleeve 82 mounted in the top frame plate ll. Afiixed to the upper freeend of said journal 9! is a driving sprocket 93. Mounted in connectionwith the bottom frame plate H1 is a journal stud 94 to rotatably supportthe lower end of said female crimping roll 89 in connection with asuitable anti-friction bearing 95 with which the latter is provided. Atthe upper end of the other roll, e. g. the male crimping roll 96, is ajournal 96 which extends upwardly through a bearing sleeve 8'! supportedby an adjustable bearing carrier 98, and, at its lower end, said roll isprovided with an anti-friction bearing 99 in connection with which it isrotatably supported by a journal stud I00 carried by a correspondingadjustable bearing carrier IOI. The bearing carriers 38 and IIJI arerespectively slidably mounted upon the top and bottom frame plates formovement between guide-pieces 64, and

; the adjusting movements of said carriers are controlled by adjustingscrews I02 which are threaded through stationary brackets I03respectively affixed to said top and bottom frame plates. By adjustablymoving the bearing carriers 98 and IBI, the adjustable crimping roll maybe moved toward and fromv the stationary crimping roll so as to properlyrelate the same in spaced opposition to pass the foil fringetherebetween in such manner as to effect the desired crinkling of theindividual fringe elements by pressing the latter between the matingmale and female annular corrugations with which the crimping rolls areprovided. A drive sprocket I04 is affixed to the upper journal 96 ofsaid adjustable crimping roll 90. At its upper end portion said malecrimping roll is provided with a plurality of circumferentially spacedradially projecting drive pins I05 to engage and propel the tape boundmarginal portion of the foil through the crimpling rolls. The crimpingroll 89 is provided at its upper end portion with an annular clearancegroove or channel I06 to receive and pass the drive pins I05 of crimpingroll 90.

After passing through the fringe crimping means, the decorative materialis completed and is passed to any suitable mechanism (not shown) forwinding or folding up the same or otherwise arranging it for packagingready for commercial distribution.

It will'be understood that in cases Where itis desired to furnish thedecorative material with straight and smooth or uncrinkled fringe, thecrimping rolls may be withdrawn from service position or omitted.

Illustrative of one form of driving means for transmitting operativemovement to the several sets of rolls, included in the functionalmechanisms of the machine, there is shown a chain drive IB'I whichengages the several sprockets with which the various roll devices areprovided. A selected journal of one of the roll devices may be utilizedas a drive shaft. For example, the upper journal 9i of the crimping rollis provided with a shaft extension I33 to which an electric motor (notshown) may be connected in driving relation thereto, or, in fact, anyother means for transmitting operating power to said shaft extension maybe employed. "I'he drive chain It'll is driven in a clockwise direction,i. e. in the direction of the arrow :0 appearing in Fig. 2. The chain isrun exteriorly around the drive sprocket 93 of the female crimping roll8Q and then back and exteriorly around the drive sprocket I04 of themale crimping roll; thence the chain runs exteriorly around the sprocket81 of the backing roll I8 and then back and exteriorly around thesprocket T3 of the cutter roll lil; thence the chain runs exteriorlyaround the sprocket 59 of feed roll 55 and then back and exteriorlyaround the drive sprocket Bl of the feed roll 55; thence the chain runseXteriorly around the sprocket 53 of the pressure roll 40 and then backand exteriorly around the sprocket 42 of the other pressure roll 39; andfinally the chain runs around a tensioning sprocket I99, which ismounted in connection with the top frame plate ii, and then to andaround an idler sprocket Hi3, also mounted on the top frame plate It,thence returning to sprocket 93 aforesaid. All this will be understoodto best advantage from an inspection of Fig.

2 of the drawings. It will be obvious that the cooperating rolls of eachset of roll devices will be rotated in opposite directions by theabovedescribed drive chain arrangement, whereby the various roll setswill function to advance the materials operated upon from one roll setto another while subject to the functional effects of the respectiveroll sets.

While the above described chain and sprocket drive means provides asatisfactory power transmission means for actuating the several rollsets of the machine, it will nevertheless be understood that such formof transmission means is illustrative of but one of many other forms ofpower transmission which might be employed. For example, instead of thechain and sprocket drive, a system of gearing could be employed, as willbe readily understood by the skilled mechanic.

The transmission is located above the top frame plate as will be seen,and it is desirable to g,

guard the same, both to protect it and to safe-- guard the operator ofthe machine from possible injurious accidental contact therewith. Tothis end a covering guard plate III may be provided to extend thereover;said guard plate being supported upon carrying posts H2 secured to andupstanding from said top frame plate II.

The functioning of the several roll sets and the operation of themachine as a whole in carrying out its intended purposes will beunderstood, it 1 is believed, without need for further amplification. Itwill be obvious, however, that the machine may be used for the intendedpurposes in connection with various kinds of sheet material in additionto the foil material above mentioned. It will also be understood that,if desired, the incorporation of a reenforcing cord with the boundmargin of the finished material may be omitted when its presence in thefinished material is not desired.

Referring to Fig. 9, there is shown therein a modified form of foilguide rod which may be employed in place of the solid guide rod 30 whichseparates the unwinding course of the foil from the supply roll. Thismodified foil guide rod comprises a hollow or tubular rod II3 providedin its side walls with a series of discharge openings H4. Air under somepressure may be supplied to the interior of said rod H3 for dischargefrom the openings H4 toward the periphery of the foil roll adjacent tothe point of separation of the run of foil being drawn therefrom. Suchdischarge of air tends to aid the separation of the foil run from theroll so as to assure against impedance of the proper movement of thefoil from 1 the supply roll from any cause.

It will be obvious that many changes, in addition to those hereinabovereferred to, could be made in the above described construction, and thatmany apparently widely different embodiments of the invention could bemade without departing from the scope of the same as defined by thefollowing claims. It is therefore intended that all matter contained inthe above descrip tion or shown in the accompanying drawings shall beinterpreted as illustrative and not in a limiting sense.
